Need advice on a corporate ethics issue.

​

A friend of mine works in a Big 4 company and has around 3 years of experience. She submitted multiple reimbursement claims over time (mostly meal and travel expenses) using fake invoices. Total amount is around ₹70k–80k across 10+ smaller claims.

HR initially emailed her regarding the issue, but she did not respond out of panic. The matter has now been escalated to the Ethics Committee. She is willing to repay the full amount immediately and cooperate fully.

She understands the seriousness of what happened and is prepared to accept consequences, but wants to know what realistic options she has to avoid a formal termination for misconduct and protect her future career as much as possible.

Has anyone seen similar cases in corporate India / Big 4?

What usually happens in situations like this — repayment + resignation, termination, or any chance of leniency?

Serious advice only, please.
